Baume Mercier Clifton 10839

The high-tech Clifton 10839 movement rounds out the beauty and refinement of this exclusive timepiece. The self-winding Baumatic Manufacture movement drives the mechanism in an exceptionally precise stride. It offers a strong resistance to everyday magnetic fields, up to 1500 Gauss, and its chronometer is certified by the COSC (Swiss Official Chronometer Testing Institute). It trots steadily to a frequency of 4Hz (28 800 vph). The caliber offers a remarkable freedom of autonomy thanks to its five-day (120-hour) power reserve, and is water-resistant to 5 ATM (approximately 50 m).
